# Conditions needed for reaction between FeCl3 and KI

$$\ce{FeCl3 + KI + H2SO4 -> ?}$$

For the reaction to proceed, is it necessary to have the medium acidified, here with sulfuric acid?

No, it does not, you can drop $\ce{H2SO4}$ from the equation. However, in practives it is necessary to acidify $\ce{FeCl3}$ water solutions to suppress hydrolysis.
